Historically personnel with PPE and breathing apparatus would enter the tank and manually clean using pressure washers. With more emphasis on Health and Safety, we have developed systems that include one of our high pressure pumpsets that feeds a tank cleaning nozzle which is water powered and rotates in two planes to bring about total, automatic cleaning of the entire tank surface. The nozzle has adjustable rpm which enables the cleaning cycle to be adjusted between 5-60 minutes.
The nozzle can be lowered into the tank from a hosereel and locked in position for the cleaning cycle. In larger tanks the nozzle can be fixed at 2 or 3 different heights.
